In the construction shown, said pulleys j' are in the form of ringsprockets, the internal diameter of which is supported by flangedrunners j3 mounted on a plate j* outside the chain, said plate beingmounted on the spindle o of the main chain pulley j1 and held by studsextending from the framing n. Adjustment of the chains may be producedbv mounting the spindle 0 of said pulley j1 in a slide block o1 adaptedto slide on guides 02 in the framing n and under the action of a screw03. Y

The plate j* is part of or fixed to the slide block forming the flange,thereof, and it is provided to make a support for the guiding chainpulley j2 so that it can be adjusted with the main driving chainsprocket. Where there is no adjustment the roller bearing pins are fixedto the side frame of the prover.

Fig. 7 shows the construction adopted in mounting the receptacles a onthe main chains b1, a bracket p being mounted at each side on thespindle a and carrying the receptacle shown in the form of a tray ontheir upper surfaces, the tray having depending fianges o3 topreventshifting.

Other means may also be adopted according to requirements so long as theprinciple outlined, viz. the use of an auxiliary or guide tetonas chainfor the tained.
